The Milesight EM500-CO2-868M is a robust LoRaWAN® industrial air quality sensor designed to measure carbon dioxide (CO₂), temperature, humidity, and barometric pressure in harsh indoor and outdoor environments. It uses an NDIR CO₂ sensor combined with MEMS environmental sensors to provide accurate and stable air quality monitoring. With its long-range LoRaWAN® communication and ultra-low power design, it is widely used in smart buildings, agriculture, warehouses, basements, and environmental monitoring systems.
Key Features
- Measures CO₂, temperature, humidity, and barometric pressure (4-in-1 sensing)
- High-precision NDIR CO₂ sensor (400-5000 ppm range)
- Long-range LoRaWAN® wireless communication (up to ~10 km LOS)
- Ultra-low power design with up to 10 years battery life
- Industrial-grade IP65/IP67 rugged enclosure (model dependent)
- NFC-based configuration via mobile app (no wiring required)
- Supports data logging and retransmission
- Compatible with standard LoRaWAN gateways and IoT cloud platforms
- High accuracy environmental sensing for indoor air quality control
- Designed for harsh environments (dust, humidity, temperature variation resistance)
